Ottawa LRT workers rescued from tunnel construction site

City officials say “a minor construction incident” temporarily trapped three workers late Thursday afternoon after some reinforcing steel came loose in Ottawa’s light-rail tunnel near the University of Ottawa.

John Manconi, the city’s general manager of transportation services, said in a statement that no part of the tunnel itself collapsed.

He said workers were applying concrete to the side wall of the tunnel when some steel fell and came to a rest on the workers’ lift, which required them to seek assistance to lower it safely.
